"Qli", known as "Qliphort" (クリフォート Kurifōto) in the OCG, is an archetype of EARTH Machine monsters introduced in The New Challengers that are designed to take advantage of the Pendulum Summon mechanic. This is reflected in the eye-shaped motifs visible in their appearances; these motifs are flanked by two crystals, one blue and another red, that are identical to the indicators of a Pendulum Scale. In the TCG, "Qli" monsters all contain the term "Qliphort" in their names, despite card texts using the more general "Qli" name.
